Fig. 5 is a kind of schematic diagram of the gate system for sample detection shown according to another exemplary embodiment.Such as Shown in Fig. 5, the course of work of the gate system 10 for sample detection can be for example as described below：
It waits for that ticket/IC card/identity card 1 being inserted into the bayonet of ticket card slot 1022 to be measured by the personnel of gate, bayonet one Side is provided with spring top bead 1026, and it is good that spring top bead 1026 can force ticket/IC card/identity card 1 to be contacted with cleaning sampling band 1042 It is good.Cleaning sampling band 1042 motorized pulleys 1044 driving underdrive, meanwhile, cleaning sampling band 1042 will also drive ticket/IC Card/identity card 1 moves synchronously, and coupon information reader 1024 to be measured reads and veritifies coupon information to be measured, waits for ticket/IC card/body Part 1 contact of card is after the shrapnel 1028 of 1022 end of ticket card slot to be measured, and shrapnel 1028 is by ticket/1 ejecting card of IC card/identity card Slot, passenger or related personnel can take out ticket/IC card/identity card 1.Simultaneously to ticket/IC card/identity card of passenger or related personnel 1 wiping sampling process terminates.
The cleaning sampling band 1042 for being adsorbed with certificate sample continues to be driven under the driving of motor, and is sampled by cyclone Above device.Wherein, 1068 outer surface of cyclone sampling head is equipped with heating film, and heat-preservation cotton is covered with outside heating film, purified Air or nitrogen are rotated from center after inner cavity, exocoel heating respectively again respectively from four air inlets of cyclone sampler lower end Airflow exhaust outlet 1064 and peripheral swirling eddy outlet 1066 rotate discharge.Wherein, through peripheral swirling eddy outlet 1066 Discharge is big flow high speed rotation air-flow, is primarily used to form cyclone local decompression；Through center swirling eddy outlet 1064 discharges are low speed high temperature gas flow, are mainly used for heating cleaning sampling band 1042, and sample is forced to desorb.Wherein, it is increasing Strong cyclone vacuum effect, tubaeform sampling head-shield 1069, tubaeform sampling head-shield are provided on cyclone sampler top 1069 can be focused cyclone, enhance cyclone vacuum effect.Between tubaeform sampling head-shield 1069 and cyclone sampler It is fixed using O-ring seal 1067.The sample being precipitated is sampled in cyclone sampler negative pressure and 1062 lower end of sampling air entry The semi-permeable membrane of device 108, chromatographic column and transference tube analysis detect after testing under air-breathing pumping action.
It is applied widely according to the gate system for sample detection of the application, volatile-resistant substance can be carried out fast The sample detection of speed.It is suitable for airport/highway/railway critical point, the scene that the personnel such as convention admission pass through quickly is checked, more Traditional sampling mode has been mended to the problem of the sampling hardly possible of the volatile-resistant substances such as drugs, explosive and accuracy of detection difference etc., has been started The new model of trace materials clearance examination.
It will be appreciated by those skilled in the art that above-mentioned each module can be distributed according to the description of embodiment in device, also may be used Uniquely it is different from one or more devices of the present embodiment with carrying out respective change.The module of above-described embodiment can be merged into One module, can also be further split into multiple submodule.
Fig. 6 is a kind of flow chart of sample survey method shown according to an exemplary embodiment.
As shown in fig. 6, in S602, reads and veritify the information for being placed in the ticket to be measured in the storing apparatus.Pass through Gate system reads and veritifies the information for being placed in the ticket to be measured in storing apparatus；The gate system includes：Storing apparatus is used It is placed in the information of the ticket to be measured in the storing apparatus in reading and veritifying；Wiping and sampling device, including：Cleaning sampling band, The cleaning sampling band is carried out for driving the ticket to be measured to be moved in the storing apparatus, and to the ticket to be measured Cleaning sampling；Sampling apparatus, for collecting the sample fallen from the wiping and sampling device；And detection device, for pair The sample is detected, and exports testing result.
In S604, cleaning sampling is carried out to the ticket to be measured by the cleaning sampling band in wiping and sampling device.
In S606, by air-flow by sample by being blown off on the cleaning sampling band, and collect from the cleaning sampling band On the sample that falls.
In S608, the sample is detected, exports testing result.
According to the method for the sample detection of the application, R. concomitans have a height boiling point sample to the especially difficult volatilization of sample Product sample the good wiping sampling mode of effect, and with the cyclone sampling configuration efficient to gaseous sample sample collection. Both sampling modes are used in combination, on the one hand avoids and directly IC card piece, identity card etc. is directly heated and to certificate etc. Hurtful risk, on the other hand compared to traditional Thermal desorption and air-breathing sample mode, not only using cyclone sampler Design is simplified, and even better to the more traditional aspirated mode of sample collection effect being precipitated.
